Sandi seems to be advising against Sandi's rules, which is why I ask for clarification of the (non-) subtleties of boundaries in conjunction with LRT.
Could you explain how I have advised against Sandi's rules? I may have not made myself clear in something I was trying to explain, but I don't remember contradicting any of the "rules".
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
